Extracted text: Consider the global reaction of formaldehyde (CH20) with 150% excess air. If the reaction take place at 1000 k at which temperature the molar enthalpy of formaldehyde is -81053 kJ/kmol. And assuming a complete chemical reaction (CO2, H,O, 02 and Na). And by using the thermodynamics tables attached if necessary and the table of heat of formation from your slides. Determine the heat of reaction and determine whether this reaction is endothermic or exothermic Ideal-gas properties of nitrogen, N, (Cor Ideal-gas properties of axygen, 0, (Concl Ideal-gas properties of carbon dioxide, CO, T.
